More bling for my daughter's hair and simple enough she can do it herself.  It's just basic elastics and material.  I cut the material into 8 inch by 1 inch strips.  Tie it on with a loop and pull the ends through.  Pull it tight and it will pop when you get it full. 
Put on as many ribbons as you want.  It is all dependent on how full you want it to be when its on.  This is what I did.  I used 15 ribbons of material tied on for 30 strands sticking out. 
This is what it looks like in her hair.  She loves the poof of color and the tiny sparkles on the material.  It was made of scraps I had around the house and basic hair elastics.  Total cost was under $1 per set.
